Specification of Letters Patent.

Patented July '7, 1908.

Application filed September 30, 1907. Serial No. 395,271.

To all whom it may concern:

Be it known that I, WILLIAM J AY BARBER, a citizen of the United States, residing at Honeoye Falls, in the county of Monroe and State of New York, have invented a new and useful Combined Atomizer and Powder Distributer, of which the following is a specifiin accordance with my invention.

cation.

This invention relates to a combined atomizer and powder distributer for applying liquid or powdered insecticides upon trees and other vegetation.

The object of the invention is to provide a tank or receptacle having a pump opera tively connected therewith and provided with independent atomizing and powder distributing nozzles, said nozzles being operatively connected with the receptacle and adapted to discharge the contents thereof when the pump is actuated.

A further object of the invention is to provide a terminal hood or chamber having s aced depending tubes communicating t erewith and extending within the tank or receptacle, said hood being provided with a removable cap or closure for controlling the flow of air to the receptacle.

'A further object is to provide the tank or receptacle with an interior cup or pocket for the reception of the liquid insecticide so that the lower end of the atomizing tube may be submerged in the liquid regardless of the position. of the tank or receptacle.

A still further object of the invention isto generally im rove this class of devices so as to increase t eir utility, durability-and efficiency.

Further objects and advantages will apear in the following description, it being understood that various changes inform, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification: Figure 1 is a slde elevation partly in section of .a combined atomizer and powder distributer constructed Fig. 2 is a top Ian view ofa portion of the same. Fig. 3 is a front elevation partly in section. Fig. 4 is a detail longitudinal sectional view showing the device used as a owder distributer. 5 is an enlarger detail sectional view 0 a portion of the pump piston. Fig. 6 is a face view of the piston.

Similar numerals of reference indicate cor- I responding parts in all of the'figures of the drawings.

The improved device forming the subject matter of the present invention includes a tank or rece tacle 5 preferably circular 1n contour and ormed in sections the adjacent edges of which are over-lapped and soldered or otherwise united, there bein a flat bar 6 extending transversely across the bottom of the receptacle to form a support for the same, as shown.

The upper section of the tank or receptacle is formed with a semi-circular seating recess 7 for the reception of a pump cylinder 8, the latter being soldered or otherwise rigidly secured to the rece tacle and having its exteriorwalls threade at 9 for engagement with a correspondingly threaded cap 10.

Mounted for reciprocation within the pump cylinder 8 is a piston rod 11 which extends through the gland or bushing 12 of the cap 10 and is provided with a terminal operating handle 13 having an annularstop collar or shoulder 14 for limiting the longitudinal movement of the piston 15.

Engaging the exterior walls of the pump cylinder 8 is a longitudinally disposed air tube 16 preferably triangular in cross section, as shown, and having one end thereof communicating with the interior of the cylinder through an aperture 17 with the opposite end thereof communicating with a valve chamber 18 by means of a similar aperture 19, there being an aperture 20 formed in the opposite wall of the valve chamber 18, as shown.

Arranged within the valve chamber18 is a flap valve 21 adapted to alternately close the apertures 19 and 20 when the piston 15 is reciprocated.

Arranged at the forward end of the pum cylinder is an intake valve 22 through which air enters when the piston is retracted, there being a similar valve 23 formed in the threaded cap 1( through which air is admitted into the cylinder when the iston 15 is moved in the direction of the tan or receptacle.

Secured in any suitable manner to the front end or wall of the ump cylinder 8 is a substantially cylindrical hood 24 having an openin or aperture 25 formed in the rear wall thereof and communicating with the interior of the valve chamber 18, as shown.

Disposed within the chamber of the hood 24 is a depending atomizer tube 26 the u per end of which is disposed in' horizontal a inement with the aperture 25 while the lower end thereof extends within a cup or pocket 27 secured in any suitable manner to the interior walls of the lower section of the tank or receptacle. V

By arranging the cup 27 within the tank or receptacle the lower end of the atomizing tube will be submerged in the liquid regardless of the angle or inclination of the tank, it being here noted that the mouth of the cup is contracted while the bottom thereof is inclined towards the adjacent wall of the lower tank section.

Extending laterally from the upper section of the tank or receptacle are s aced nozzles 29 which communicate with t e interior of the tank and through which the insecticide is discharged when the device is used as a powder distributer.

Extending through the lower wall of the hood 24 and preferably projecting a short distance above said wall is an air tube 30 the lower end of which communicates with the interior of the tank or receptacle so that when the device is used for distributing owder the air from the chamber of the hood will be forced downwardly in the tank and thus discharge the owder in the receptacle laterally through tlie nozzles 29.

The exterior walls of the hood 24 are threaded for engagement with .the corre s ondingly threaded cap 31 which forms a c osure for the open end of the hood and thus serves to direct the air downwardly through the tube 30 into the tank or receptacle when the cap is in position on said nozzle.

The u per section of the tank is rovided .with a'filling orifice through which t e liquid or owdered insecticide is introduced into sai receptacle, said filling orifice being normally closed by a stopper or other slmilar closure 32.

The piston head 15 consists of a central disk 33 having washers 34 bearing against the opposite faces thereof with their peripheral edges flared laterally for engagement with the interior walls of the pump cylinder,

7 there being substantially triangular plates 35 bearing against the washers and provided with terminal laterally extending hooks 36 for engagement with an ex vansible ring or band 37. The rings or banc 37 bear against and yicldably support the flared edges of the flexible washers in engagement with the walls of the pump cylinder and thus serve to prevent leakage.

Suitable disks or plates 38 bear against the plates 35 and are retained in engagement therewith by clamping nuts 39 threaded on the adjacent end of the piston rod 11, as shown.

When the device is used for atomizing urposes the liquid insecticide is introduced into the receptacle through the filling orifice and the cap or closure 31 removed from the hood '24 after which the piston 15 is reciprocated valve chamber 18 thus moving the valve 21 seams within the pump cylinder by manipulating the handle 13.

As the piston 15 is moved in the direction indicated by the arrow in Fi 1 of the drawings the air will be admitte in front of the piston throu h the valve 22 while the air at the rear of t e piston will pass through the aperture 17 into the longitudinal tubes 16 and thence through the aperture 19 into the to close the apertures 20 and forcing the air through the aperture 25 into the chamber of the hood 24. As the air passes over the free end of the atomizin tube 26 the liquid in the com artment 27 wi 1 be drawn or sucked upwarc ly through the atomizing tube and thus be delivered upon the plants or other vegetation in a finely atomized condition. On the return stroke of the iston 15 air will be admitted to the rear 0 the iston through the valve 22 while the air at t e front of the piston will be forced through the aperture 20 into the valve chamber 18 and thence through the aperture 25 to the atomizer noz zles thereby rendering the device continuous in operation.

When the pump is used for distributing owder or other finely (livided'material the liquid is removed from the tank and the latter thoroughly dried after which the owdered insecticide is introduced in the filing orifice and the cap or closure 31 placed in position on the hood 24 so as to form a closure for the front end of the hood, as best shown in Fig. 4 of the drawing. 1

When the parts are thus assembled and the pump is operated the air entering the chamber of the hood through the valve chamber 18 will come in contact with the closure 3 1 and thence be directed downwardly through the tube 30 into the interior of the tank or receptacle thus discharging the powder through the nozzles 29, as will be readily understood.

I Attention is here called to the fact that when the device is used for atomizing purposes and the liquid in the cup 27 is partially or totally consumed the cup may be again refilled by merely tilting the tank which causes the liquid in the latter to flow into the on 27, the operation being continued until all of the liquid in the tank has beenconsumed.

From the foregoing description it is thought that the construction and operation of the device will be read-ily'understood by 12) those skilled in the art and further descrip tion thereof is deemed unnecessary.
